Oh Mike... Mike, why did you have to get me in trouble? I used a little more butter than my 2nd turkey. I would GUESS 1/2 cup with the spices mixed in, it was just enough to cover the whole breast and two legs, before pinning the skin back down.
My McCormick rub came in a 3.25 oz container and I used 1/4 of it. Now I would say a pinch of the other spices, maybe 1/2 tsp at the most. This really would be up to the individual that was eating/cooking the bird. My 2nd bird I only used the McCormick rub and thought it really needed a little more pepper and salt taste for this bird.
Yep!, it all comes down to practice so don't wait until the last minute to do your bird!
